Application M21729;

1936, Serial No. 82,450

3 Claims. 225- 21),

This application relates to a beverage dispenser of the type in which a beverage is displayed through a transparent portion of the chamber that contains it.

The dispenser of this application is adapted to display a beverage. producing a fountain like spray of beverage near the top of the container, which spray then falls like rain into the lower part of the container. of the beverage keeps up this display as long as desired.

The object of the invention is to provide a dispenser which presents a pleasing appearance, makes an attractive display, keeps a beverage cold, provides a. simple mechanism which operates for long periods without need of repair, and which makes the operation by a vendor simple. Economy is attained by the use of dead air as an insulation against heat transfer between two transparent glass bowls of the container, dead air being almost as good an insulator as a vacuum.

The device is adapted to handle such beverages as fruit juices or milk which must be kept agitated so they dont separate into their con-- stituents.

Heretofore in dispensers of this kind trouble has been experienced with clogging of circulating pumps with the pulp found in fruit juices and with corrosion of pumps and contamination of the beverage by contact with the pump or its lubricants.

The present dispenser therefore makes use of an antiseptic rotary pump similar to those which have been used in medical science.

The present embodiment of the invention is illustrated in the accompanying drawings. in which:

l. is a general view of the dispenser as it might rest on a merchants counter;

Fig. 2 is a fragmentary view showing the front half of the outer glass shell cut-away to show the construction:

Fig. 3 is a section on lines 3--3 of Fig. 1; Fig. 4 is a section on line 4'-4 of Fig. 3 showing a detail of fastening;

Fig. 5 is an enlarged view of parts of the re- 7 filling valve;

Fig. 6 is a section on lines 6-6 of Fig. 5; Fig. 7 is a section through the pump;

Fig. 8 is a top view of the pump with the cover removed; I

Fig. 9 is a top sectional view through the pump on lines 9-9 of Figure 7.

On a base i2 which contains the actuating devices of the dispenser. rest two clear glass shells i0 and ii through which a fountain spray of beverage is visible when the circulating pump is in operation. These shells are both of circular Continuous circulation refrigerant lines. I

built into the line. is a hollow part 62, adapted cross section closed at the top by a hemispherical portion, and are dispose-done within the other.

At the bottom of each shell is 2. turned up portion forming a foot or flange on which the shell rests. The flange ll of the outer shell is set in" rubber on the base and is covered by a chrome plated trim ring i5.

The flange 21 of the inner shell ll rests 'on a flange 28 of a metal bowl 22. which comprises the lower part of the beverage chamber, the inner shell H being the upper part. Flange 21 is separated from flange 28 by a rubber compres-' sion ring or gasket 26 which forms a secure liquid seal when the two chamber parts are pressed together. These parts are pressed together by means of a nut I6 on a threaded rod" which is disposed within tube l8 and secured to same I at a point near the bottom of bowl 22.

The base i2 is a thin-walled, hollow metal cylinder. 7

vide a shelf 13, in the shape of a disc like ring,

At thetop lt is formed sons to proadapted'to support'the glass i0 and the flange 3 28 of the bowl 22. Fastened to the bowl 22 is a belt 29 which provides the space 2i, comprising an evaporator unit of a refrigeration system. The inlettube 23 is at the bottom. an expansion valve 63 is located in the tube 23 immediately before the evaporator, and the outlet 24 is located at the top of the chamber and at the op posite side from the-inlet. The other units of a. refrigerating system connecting with 23 and 24 may be placed under the counter on which the dispenser rests or in. another part of the building, or these connections may be made to any Attached to gas line '24, or

Also contained-in the base l2 are the pump 40,

the refilling valve 50, and the necessary connectlons' between the various parts. The pump 40 is of the rotary type and more particularly may be called an antiseptic orjinsulated' rotary pump, since the beverage passesthrough while in a rubber hose. A shaft 39. is journaled in wall 4|, and integral with an eccentric 44, on which a roller 42 revolves on roller. bearing 43'. A soft rubber tube 45 is disposed within the casing cylinder 46. The relative dimensions 01' eccentric roller, tube, and casing are such that the eccentric squeezes the tube walls together at the point, such as 41, farthest from the center of pump shaft 39, stopping flow through the tube at this point 41. This condition glues the effect of a shut-oifvalve when the pump. is not running. However, when the pump does run, the same condition circulates liquid through the tube 45. The eccentric, gyrating about its shaft, flattens the tube at progressive points in itscircle, that is, at all points of the tube progressively and at each point instantaneously.- Any fiuid contained in the tube is therefore forced through same. As the eccentric pushes the liquid through the tube ahead of it, more. liquid flows into the tube to fill the space left vacant venient electric outlet.

by the opening tube in the wake of the eccentrics high spot. Every time that the high point of the eccentric passes the crossing point I of the tube 48 it begins toforce a new tube full of liquid through the tube. The pump is therefore a positive displacement pump. It is driven by an electric motor I8, connected toany con- The roller bearing 43 has been added to insure that the eccentric does not move the tube 45 in its casing, but merely rolls over it while flattening it.

The refilling valve is designed to permit normal flow through the return line to the suction side of the pump and to stop that flow when desirable and permit the pump to draw additional liquid into the system. Mounted near'the wall oi the base is a T connection .5l. ,The drain line 52 from thebeverage chamber is connected to one side of the T, the suctionline- 53 of the pump is connected to the second side and a refilling tube 54 is connected to the third side. The refilling tube projects through the base wall, and is normally capped. Fastened to the T- by two straps 55 and 56 is a rod 51 having a handle 58 outside of the base and having a cam 59 at its other end. Also fastened to the T by strap 55 is anvil 60; When handle 58 is moved to turn, rod 51, the cam 59 is urged toward the anvil 60, compressing the tube 52- and stopping all flow in the tube. An arrangement may be added for holding thecam 58 in this closed position, or the tube may be held closed by a continuous pressure on handle 58.

Normally the flow through the T is from tube 52-to tube 53. Whenit is desired to refill the dispenser, however, the handle 58 is actuated to close tube 52 by means of cam 58, cap Si is then removed and a beverage supply is connected with fill pipe 54. Operation of the pump then .draws the beverage through tubes 54 and 53 and forces it through tube 38 and tube l8 into the display chamber.

For withdrawing, or dispensing, the beverage there is provided a faucet 55, supported by the wall of base l2, and connected through tube '66 to the bottom of the beverage chamber at 61. When the faucet is opened by turning handle 64, the beverage flows through it, infiuenced by gravity. 4 Y 8 Projecting through the bottom of bowl 22 is tube l8 which provides for the beverage a spectacular entry into the chamber. The tube I8 is securely fastened to the bowl for support and is sealed in to prevent leakage. The tube extends to a point near the top of the beverage chamber and is connectedat the bottom with the discharge line 38 of the pump. The rod H which passes through the tube is secured to beverage projected by tube ll.

plate I9 is screwed to rod l1 and is. advanced spray tube.

the tube at a point below the level of the glass T by a rod 86 which passes through holes in the tube and through an eye 54 formed in end of the rod.

On the upper part of the rod I! immediately below the top of the glass is a deflecting plate l9 whose purpose is to redirect .the stream oi to such a point'that it forms a shoulder for a gasket-82 which, with another gasket 85, permits nut ii to seal the hole 25 in shell ll through which the rod I'I passes as well as to press shell ll against flange 28 at its lower end. A vent is provided to allow maintenance of atmgmpheric pressure in the chamberwith varying amounts .oi'fbeverage present This is ac- This deflecting complished by a hole 85 drilled through nut. Il

But the air thus admitted to the space between the shells is confined within a tube. 81 whose lower end fits over nut l8 and whose other end is pressed against outer shell I. The air of the chamber communicates withthe outside air through a small hole 89, inthe top of shell ll.

As has been mentioned above, flange l 4 of shell 10 is air-sealed to shelf l5 of'base l2. ,As has also been mentioned, the beveragechamber restswith its flange on shelf ll. Therefore a fairly good air seal is secured at the bottom of they space between the-shells. Furthermore.

a ring 20 is supplied to mask the joint 26, 21,

28 and the space between this ring and the Joint is filled with mineral wool insulation. Thus a dead air space is secured to insulate against excessive v heat loss into the .Elass chamber.
